ModuleNotFoundError: No module named 'cfg'

This error message indicates that Python is unable to find a module named 'cfg'. This could be due to one of the following reasons:

1. The module is not installed in the Python environment: You can try installing the module using pip or conda depending on your Python environment.

2. The module is not in the correct directory: Ensure that the module is in the same directory as the Python file that is trying to import it.

3. The module name is misspelled: Double-check the spelling of the module name to ensure that it matches the import statement.

4. The module has not been added to the Python path: You can try adding the module to the Python path by appending its directory to the PYTHONPATH environment variable.

Once you have identified the cause, you can take appropriate steps to resolve the issue.
